This lesson introduces proportional relationships through various activities, including adjusting recipes, calculating park entrance costs, comparing running times, and analyzing costs of apples and pizza. The lesson emphasizes constructing tables to understand proportional and non-proportional relationships, using constant rates, and applying these concepts to real-world scenarios.

• The cost per topping decreases as more toppings are added

What is the key factor in determining if a relationship is proportional?

• The presence of a constant of proportionality

• The complexity of the equation

• The size of the values involved

• The number of variables
